¿Cómo sabemos lo que sabemos?
The deep history of Earth and life, with the evidence chain visible behind every claim.
🇲🇽 In Spanish · built for LATAM
A reading platform on how we build reliable knowledge about the cosmos, Earth, life and humankind — from first principles. 53 investigations with the inference chain in plain sight (claim → evidence → source → method), all open and citable (CC BY 4.0). Rigor without false certainty.
The problem
What it solves
About the remote past —the cosmos, the Earth, life, humankind— there are textbook certainties and also myths. There's no place that shows HOW we know each thing, not just what we think we know.
The solution
How it solves it
A reading platform that reconstructs deep history from first principles and keeps every claim's inference chain visible: claim → evidence → source → method → data.
The difference
Why it's different
Rigor without false certainty: it shows the competing explanations, flags what isn't known yet, and everything is open and citable (CC BY 4.0). It appeals to evidence, not authority.
The intelligence
How AI comes in
The knowledge and the writing are human and traceable; AI is the builder's scaffolding (organize, verify citations, move faster), never the voice that asserts. Trust lives in the sources, not the model.
